the ends of each of these arme journaleil a guide roller et, similar to that which is mounted directly upon the end ol section 11%. rlhe pivot pins tor all oi these rollers prei'- erably project slightly beyond the'tace oit the roller, this end being adapted to contact with the rib 25, `so as to hold the shifter trame securely in'position and prevent its rockin".

Each frameL is supported from three points, said points consisting of the three rollers. The two rollers carried by the arm-s 13 and let, in coperation with the end bearing of the `pivot Jfor the lower roller, prevent twisting of the frame in a horizontal plane. The lower roller cooperating with the end bearings of the pivot pins tor the upper rollers prevents lateral rocking upon the lower roller. A rocking of the shifter frame in the planeetl the saw. is prevented by the same contacts.l

The triangular recess which exists above the flange 21, I prefer to cover by a thin plate 5, of sheet metal. This prevents shavings and chips accumulating yin this recess. AS the guide bearings for the shifter frames are all under and thoroughly covered by the 'Hang-e 2l, there is small possibility of dust getting on these guideways and preventing smooth` working of `the device. l

AI claim as my inventiony 1. A guide frame for saw shifter mechanisms having connected vertical and hori- Zontal webs with the apex oit the angle between them toward the saws, the vertical web having one set of guiding surfaces andv the horizontal web having two sets of guiding surfaces, said guiding surfaces being parallel to the plane of one or the other web and being atthat side ot the webs which face inward o'll the angle between them.

2, A guide frame for saw shifter mechanisms having vertical web and horizontal web placed with the apex of the angle formed thereby toward the saws, the low r edge of the vertical web having` a rib projecting into the angle included between the webs and provided with an upwardly facing guide surface, and the lower surface of lthe horizontal web havingtwo grooves therein lacing downward, the side surfaces oit said grooves forming parallel guiding surfaces.

3. guide frame 'for saw shifter mechanisms having connected. vertical and horizontal webs placed with the lapex of the angle between them toward the saws,ithe inner side of the vertical web yhaving twV guiding surfaces toward its lower edge and lying, respectively, in a vertical and in a horizontal plane, the under surfacekof the horizontal web having two guiding channels ch oit said cha' -ls having a cen ndig el'lr'lace lying' in a horizontal opposite edge guiding surfaces ying in parallel vertical planes,

ln an edger guide, in combination, a tranrlwersely extending beam having a herizontal web and a vertical web placed with the angle betwee said webs away from the saws, three guideways carried by the inner faces oi said webs, a shifter frame having three guides separated to coincide with the apices et a triangle and engaging each its respective gnideway or said beam.

5. ln an edger guide, in combination, a transversely extending beam having a. horiw zontal and a. vertical web, the horizontal web having two channels in` its 'under side havingjiiarallel sides and the vertical. web havinga guidewaj-,f along its lower edge at the side facing toward the channel-containing surface of the horizontal web, a shifter` trame having an upper section extending over the topot said beam, a section extending downward. past the horizontal web and section extending under said horizontal web, and arms extending oppositely from said last section and carrying wheels enter-V ing each its respective channel in the horizontal web, and a wheel journaled on thel frame and engaging the guidewayxof the vertical. web. n

6. ln an edger guide, in combination, a transversely extending beam having an npwardly facing wheelway extending adjacent to itslower edge and a horizontally extend ing web located upwardly of and extending over said wheelway, said latter web having two parallel, downwardly-facing channels constituting wheel guides or ltraclways, shifter trame extending over said beam about and luider the web and having arms with laterally separated ends, eachadj acent to its respective channel in the web, wheels carried upon said arms and ente-ring said channel, and a wheelmounted on the iframe and engaging the third whe-elway.

7. 1n an edger guide, in combination, a transversely extending beam having" an upwardly-facing wheelw ay ",exten-ding` adjacent to its lower edge and a horizontally extend ing. web located upwardly of and extending over said wheelway', said web having two parallel, downwardly-facing channels constituting wheel guides or traclrways, a shifter trarne extending over said beam about and under the web and having arms with laterally separated ends, each adjacent lto its` respective channel in the web, wheels and having two surfaces engaged, res ectvely, by the periphery of the roller un( by 10 the end surface of the pivotpin.
